We use LEDs from Diode Dynamics because they're the best ones we've found. They're made to high standards, not just the minimum price. They've got constant-current circuitry to protect the bulbs from transients and offer a three-year warranty.
The 921 is the correct bulb for the reverse lights on an NC Miata. Though it is the correct size bulb for the NA third brake light as well, we recommend sticking with the "cruise keeper" 3rd brake light LED shown below due to its red-light output and it has built-in resistance that allows cruise control to continue to work.
